SHEET-METAL VESSEL.

SPECIFICATION forming part of Letters Patent No. 595,800, dated December21, 1897. Application filed January 23, 1897- Serial No. 620,318. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE ACKERMANN, of Cincinnati, Hamilton county,Ohio, have invented certain new and useful Improvements in Sheet-MetalVessels, of which the following is a specification.

This invention pertains to improvements in sheet-metal vessels, such ascans and buckets, designed for containing fruit, vegetables, paint, &c.

My improvements will be readily understood froin the followingdescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is an elevation of a paint bucket or can exemplifying myinvention; Fig. 2, an elevation of the same, part diametrical verticalsection, the ripping-tool being shown in position for use; and Fig. 3, adiametrical vertical section at a top portion of the vessel, this viewbeing upon an enlarged scale.

In the drawings, 1 indicates the body of the vessel, the same being ofcylindrical form and open at its top; 2, an outward swell or enlargementon the body a short distance below the rim thereof, this enlargementbeing tapered above to form a tapering shoulder enlarging downwardly; 3,the cover of the vessel; 4, the flange of the cover, the same cappingdown over the rim of the body and fitting over the rim freely andseating snugly upon the tapering shoulder formed by the enlargement 2;5, a soldered seam at the juncture of the foot of the flange 4 with thebody, this soldered seam forming the union and closure between the bodyof the vessel and its cover; 6, a bead surrounding flange 4 and formedby outwardly beading the metal of the flange, so as to leave the flangeprovided with an inwardly-open groove; 7, a ripping-wire disposed in theinterior of bead 6; 8, the free end of this ripping-wire projectedoutwardly through a hole punched in the periphery of bead 6; 9, theripping-tool, consisting of a handled stem or key having near its end atransverse perforation adapted to engage the projecting end 8 of therippingwire; 10, a false wiring formed at the rim of the body andprojecting inwardly; 11, a downward projection given to the top portionof the cover below the plane of the top of flange 4 and extending out tonear the flange and resulting in a downwardly-open groove at the top ofthe flange, the periphery of the depression 11 fitting neatly within therim of the body, and 12 the bail.

The cover is formed separately from the body, and the ripping-wire,previously made in the form of a ring with a projecting end, is insertedin the interior of bead 6, with its end projecting outwardly from thebead. The natural expansion of the ring formed by the ripping-wire tendsto hold it in place in the bead of the cover during the general handlingof the cover, the depth of the interior of bead 6 being sufficient toaccommodate the full diameter of the ripping-wire. When the cover is tobe permanently applied to the vessel, then it is placed on the body ofthe vessel, over which it caps easily, and, being pushed home, the lowerportion of the flange fits tightly upon the tapering shoulder 2. Solderis now applied at 5 at the foot of the flange, thus permanently securingthe cover to the body, a drop of solder at the same time being appliedto projecting end 8 of the ripping-wire where it comes out of the bead,thus securing the wire and securing air-tight nose at the point where itprojects from the bead.

When the vessel is to be opened, the ripping-tool 9 is applied to theprojecting end 8 of the ripping-wire and the tool is turned so as toroll the wire up on the stem of the tool, the axis of the stem of thetool being parallel with the body of the vessel, so that as the windingtakes place the stem of the tool rolls around on the circular trackformed by the bead, the ripping-wire cutting its way through the beadand removing the peripheral portion of the bead and severing the coverat an intermediate point in the depth of the flange. The cover may nowbe removed, leaving the vessel open and with a smooth unmarred rim,adapting the vessel for use as a paint-bucket. The cover thus removedmay be at any time temporarily employed in closing the vessel, the upperportion of the flange capping freely over the rim of the body and theperiphery of depression 11 fitting snugly within the false wiring of therim and preventing liquid contents of the can from escaping through thefree space formed by the loose-fitting of the upper portion of theflange of the cover upon the rim. The operation of the ripping-Wire issuch, as before stated, as to tear away and remove the peripheralportion of bead 6, the result being that when the severed cover isreplaced upon F the can it may, so far as the flange is concerned, fitcloser down upon the rim than it did before, thus allowing the peripheryof depression 11 to be brought snugly home Within the rim of the body.

I claim as my invention- The combination of a vessel having an in-Wardly-turned rim and an outward swell below the rim, a cap or coverhaving a top depression and an exterior annular semicircular ridgefitting the inwardly-turned rim, the vertical deep flange of said coverextending downwardly into contact with said outward swell and beingprovided with an intermediate rib and counter-depression, and aripping-wire having an end projecting through a hole in the flange andits body bearing expansibly against the walls of said counterdepression,whereby the said wire is held securely in said depression during theoperations preliminary to sealin GEORGE KoKERMANN.
